What am I Looking For? o Must o Be able to describe the: fetch-execute cycle; CPU-Cache-Memory cycle; Dual processor o Should o Be able to describe how other components affect the computer speed. Create a graphical representation of the CPU- Cache-Memory cycle. o Could o Create an animation of the graphical representation of the CPU-Cache-Memory cycle.

Fetch – Execute Cycle Fetch Decode Execute

Boot Sequence ROM CPU

Boot Sequence Secondary Storage Memory CPU

Clock speed 1 second 5 pulses/second 5Hz 8 pulses/second 8Hz 15 pulses/second 15Hz

Clock speed 1 KHz = 1000 Hz 1 MHz = 1,000,000 Hz 1 GHz = 1,000,000,000 Hz

1.Describe the fetch-execute cycle 2.List 5 motherboard components. 3.List 4 factors which could make the CPU faster. 4.What is the boot sequence. 5.What is the purpose of ROM. 6.What is a dual-core processor. 7.Why a dual-core processor is faster. 8.What is a bus and what is the difference between a front side and back side bus. Answer the Questions Create a PowerPoint animation which would show how data is transferred between memory, cache and CPU. Each PowerPoint slide should be one clock cycle.

Computer A has 12 bytes of RAM and and 12 bytes cache. Computer B has the same RAM and 4 bytes of cache. Both computers operate with the same clock speed. In a PowerPoint presentation each slide is a clock cycle. The upper half of the slide is going to be used by the Computer A and the bottom half of the slide is going to be used by Computer B. A program needs to read the text “this-is-fast” and output it to upper case letters. (Just show input-output) Make an animation which will clearly show the advantage of the larger cache.
